The method may further include: calculating, by using at least one type of redundant information in the terminal, a threshold value of the at least one redundant information according to the actual redundancy value detected during the cleaning within a specified number of times.

The method may further include: calculating, at least one type of redundant information of the cleaning, a redundancy frequency of the at least one redundant information according to the cleaning period and the actual redundancy value detected during the cleaning, and according to the redundancy The frequency updates the average redundancy frequency of the pre-stored at least one type of redundant information.

In this embodiment, the terminal may include, but is not limited to, a computer, a mobile phone, a tablet computer, and a Personal Digital Assistant (PDA).

The foregoing method provided in this embodiment is configured to calculate an estimated redundancy value of at least one type of redundant information in the terminal, determine an estimated redundancy value of the redundant information to reach a critical value, and prompt the user to clean up when the estimated redundancy value reaches a critical value. Redundant information; according to an instruction provided by the user to clean up a certain type of redundant information or all redundant information, the user can actively estimate the redundant information of the terminal by analyzing the historical redundant data information of the user.

In addition, by calculating the critical value of the redundant information according to the actual redundancy value detected during the cleaning within a specified number of times for each type of redundant information in the terminal, the critical value of the redundant information can be made closer to the user's cleaning. Habits have improved the user experience.

Second embodiment

Referring to FIG. 2, the embodiment provides a method for cleaning redundant information of a terminal. The method includes:

201: Calculate, for each type of redundant information in the terminal, a redundancy frequency of the redundant information or an average redundancy frequency within a specified number of times according to the actual redundancy value detected during the cleaning period and the cleaning.

In this embodiment, the redundant information is information generated by the terminal during operation. The terminal may include, but is not limited to, a computer, a mobile phone, a tablet, a PDA, and the like. Since the redundant information loses its use value after exiting the current application, it needs to be cleaned up to improve the system performance of the terminal. There are many kinds of redundant information. In this embodiment, system garbage and system trace are taken as an example for description. Specifically, the system garbage is a temporary storage file or information automatically generated by the terminal during use, such as a temporary file of the system and the browser, an invalid shortcut, and the like. The system trace is a history of user operations automatically saved by the system for the convenience of the user during the terminal operation, such as a browsed web page, a viewed movie program, an edited or opened file file, and the like.

Usually, the behavior of the user using the terminal in a certain period of time is regular. For example, a user watches an hour of video online every day, browses half an hour of news information, spends two hours chatting with a friend online, and so on, so that the terminal is redundant. The remaining information is also regular.

Based on the above rules, the redundant frequency of the redundant information can be calculated for each redundant information in the terminal according to the actual redundancy value detected during the cleaning cycle and the cleaning, so that the candidate can be calculated according to the redundant frequency. Estimated redundancy value for redundant information. For example, when the redundant information is system garbage, if the terminal cleaning period is 13 days and the detected actual redundancy value is 131 Mbit, the calculated redundancy frequency is 10.08 Mbit/day; when the redundant information is system trace If the terminal cleaning period is 13 days and the actual redundancy value detected is 50, the calculated redundancy frequency is 3.85/day. The cleaning period is calculated according to the number of days. Of course, the cleaning period may be set to a week or a month, etc., which is not specifically limited in this embodiment.

Further, in order to make the redundancy frequency closer to the actual generation frequency of the redundant information, the average redundancy frequency can also be calculated for the redundant frequency within the specified number of times.

For example, when the redundant information is system garbage, the cleaning period and actual redundancy value of the sampling can be as shown in Table 1.

Then the average redundancy frequency = (131/13 + 161 / 17 + 110 / 11 + 181 / 20 + 171 / 19 + 140 / 15) / 6 = 9.49 (Mbit / day).

For another example, when the redundant information is a system trace, the cleanup period and the actual redundancy value of the sample may be as shown in Table 2.

Then the average redundancy frequency = (50/13 + 69 / 17 + 39 / 11 + 81 / 20 + 69 / 19 + 59 / 15) / 6 = 3.84 (bar / day).

Further, the method may further include: detecting, for each type of redundant information in the terminal, when cleaning according to the specified number of times The actual redundancy value calculates a critical value of the redundant information.

For each type of redundant information in the terminal, an average value may be calculated according to the actual redundancy value detected during the cleaning within a specified number of times as a critical value of the redundant information, so that the threshold value is closer to the user's cleaning habit. . For example, based on the above sampling data, when the redundant information is system garbage, the critical value = (131 + 161 + 110 + 181 + 171 + 140) / 6 = 149 Mbit; when the redundant information is a system trace, the critical value = ( 50+69+39+81+69+59)/6=61.17.

202: Obtain a time interval between a last cleanup time and a current time of at least one type of redundant information in the terminal, and for each of the at least one type of redundant information, according to a redundancy frequency or average of the redundant information. The redundant frequency, and the time interval of the obtained redundant information, calculate the estimated redundancy value of the redundant information.

In this embodiment, the redundant information in the terminal may be one or more types. Therefore, the redundancy value of the at least one type of redundant information may be calculated to determine whether the user is required to clear the redundant information.

This embodiment provides a calculation formula for calculating an estimated redundancy value based on a redundant frequency, that is, an estimated redundancy value=redundancy frequency*time interval. For example, when the redundant information is system garbage, assuming that the redundancy frequency is 10 M/day and the time interval of obtaining the redundant information is 16 days, the estimated redundancy value is 10*16=160 Mbit; When the redundant information is a system trace, if the redundancy frequency is 4/day and the time interval of the obtained redundant information is 16 days, the estimated redundancy value is 4*16=64; or This embodiment provides a calculation formula for calculating an estimated redundancy value based on the average redundancy frequency, that is, an estimated redundancy value=average redundancy frequency*time interval. For example, taking the average redundant frequency calculated in step 201 as an example, if the time interval of the obtained redundant information is 16 days, then When the redundant information is system garbage, the estimated redundancy value is 9.49*16=151.84 Mbit; when the redundant information is system trace, the estimated redundancy value=3.84*16=61.44.

203: Determine that the redundancy value of a certain type of redundant information reaches a critical value.

In this embodiment, the estimated redundancy value and the threshold value calculated according to the foregoing steps may determine whether the user is required to clear the certain type of redundant information. Further, when the redundancy value of a certain type of redundant information is greater than or equal to the critical value of the redundant information, the user may be prompted to clean all redundant information to improve system performance.

For example, the redundant information includes system garbage and system traces. The above data is still taken as an example. The estimated redundancy value of the system garbage is 151.84 Mbit, which is greater than the critical value of 149 Mbit, and the estimated redundancy value of the system trace is 61.44, which is larger than The critical value is 61.17. At this time, the estimated redundancy values of system garbage and system traces are greater than the respective preset thresholds, prompting the user to clean up the system garbage and system traces. Further, if the user only cleans up system garbage, when the system garbage interval is 1 day and the system garbage has an estimated redundancy value of 9.49 Mbit, the system trace interval is 17 days, and the system traces the estimated redundancy value. It is 65.24, which is larger than the critical value of the system trace of 61.17. At this time, the user is prompted to clean up the system traces or clean up the system traces and system waste.

204: When the estimated redundancy value reaches a critical value, the user is prompted to clear the redundant information.

Specifically, the estimated redundancy value of the user terminal can be notified by means of a Tips or a pop-up window, and the user is suggested to clean up immediately. For example, the content of the prompt is: It is estimated that your system has up to 990 Mbit of garbage and 300 traces of system, which has exceeded your previous endurance limit. It is recommended to clean it immediately. This embodiment does not specifically limit it.

205: According to an instruction provided by the user, the certain redundant information or the location There is redundant information to clean up.

Specifically, a cleaning option may be set for the certain redundant information, so that the user can confirm whether to clear the certain redundant information; or, all the cleaning information may be set for all the redundant information, so that the user can confirm whether Clean up all redundant information; or, you can set separate cleaning options for each type of redundant information, so that users can choose to clean up one or several redundant information. This embodiment does not limit the choice of cleaning redundant information or The way to confirm.

Preferably, the method may further include: calculating, for each of the redundant information of the cleaning, the redundancy frequency of the redundant information according to the cleaning period and the actual redundancy value detected during the cleaning, and according to The redundant frequency updates the average redundancy frequency of the pre-stored redundant information.

For example, the time period of this time is 16 days. When the redundant information is system garbage, the actual redundancy value detected is 151 Mbit, and the redundancy frequency = 151/16=9.44 Mbit/day, the updated average Redundant frequency = (131/13 + 161 / 17 + 110 / 11 + 181 / 20 + 171 / 19 + 140 / 15 + 151 / 16) / 7 = 9.48 Mbit / day to replace the original 9.49 Mbit / day; When the redundant information is a system trace, the actual redundancy value detected is 65. The redundancy frequency of this time=65/16=4.06/day, then the updated average redundancy frequency=(50/13+69) /17+39/11+81/20+69/19+59/15+65/16)/7=3.87/day to replace the original 3.84/day.

Optionally, the method may further include: updating, for each of the redundancy values of the cleaning, a pre-stored threshold value of the redundant information according to the actual redundancy value detected during the cleaning.

For example, when the redundant information is system garbage, the current cleaning value is 151 Mbit, and the updated threshold value = (131 + 161 + 110 + 181 + 171 + 140 + 151) / 7 = 149.29 Mbit, to replace the original 149Mbit; when the redundant information is a system trace, the cleanup value is 65, and the updated threshold = (50+69+39+81+69+59+65)/7=61.71, Replace the original 61.17.

The foregoing method provided in this embodiment, by calculating an estimated redundancy value of at least one type of redundant information in the terminal, determining an estimated redundancy value of a certain type of redundant information to reach a critical value of the one type of redundancy value; The value reaches a critical value, prompting the user to clear the redundant information; according to an instruction provided by the user, the redundant information or all the redundant information is cleaned, and the user may actively pass the historical redundant data information. The analysis estimates the redundancy value of the terminal redundancy information, prompts the user to process the redundant information reaching the critical value without scanning, saves system resources and user time, improves system performance, and saves User time.

In addition, by calculating the critical value of the redundant information according to the actual redundancy value detected during the cleaning within a specified number of times for each type of redundant information in the terminal, the critical value of the redundant information can be made closer to the user's cleaning. Habits have improved the user experience.
